Unhappy "Trying to guess display"

Hi everyone,

I started started using a vnc server to view the linux computers on my university from my home PC. After a bit of trial and error I figured out how to get it to work.
It's working fine, but... when ever I try to login from say for example telnet. I'm asked for my user/pass and after that it says:

Trying find a remote host
Trying to guess display
1) horse07:2 3) ec06:2 5) vpn-11-38-7:0
2) ec06:1 4) ec06:3
Select display from the above list. C-d aborts
You can also type in a display:

My question is, how can I close the displays I don't use, is it even important to do so or should I just leave it be.

Type vncserver -kill:x (where x is the session number). To use one of your examples type: vncserver -kill:2 (this would apply to horse07).

No that does not do it. That only kills the vncserver instance, but the display message remains when ever I log on. But it only happens when I log on to that computer (eq. ec06) not on any other.

In my experience, here's how using VNC works in the Linux world:
1. A user logs on to a given server -- via telnet, ssh, locally, whatever

2. That user launches a VNC server instance (by typing 'vncserver'). The first time this happens, you
are prompted for a session password.

3. The server instance starts, and the user is told what X Display it's running on. For example:
New ' (username)' desktop is
where the :1 indicates that X display 1 is used by this instance of VNC.

4. Anyone can now connect to that VNC instance by either:
Typing '' as the target in the VNC Server window, or
Pointing a web browser to ''

(would be :5902 if the X display was 2, :5903 if the X display was 3, etc.)

Is this not how you are trying to access the VNC server? I'm not sure I understand how you're trying to connect. The more I look at it, the more it looks like you're making some sort of gateway connection, and then being offered a choice of several different servers to connect to (with the option to specify one not on the list)...
